“…Together with huge advancement in PL attributes of QDs towards higher quantum yield (QY) and narrower emission bandwidth, their stability against degradable processings and conditions including repeated purication cycle, ligand exchange, prolonged UV irradiation, or thermal treatment has been steadily improved by the elaborate control on core/shell heterostructure mainly based on multi-shelling and/or thick-(or giant-) shelling strategies. [5][6][7][8] However, in the case of on-chip-packaged QD-LEDs (herein, QD-LEDs stand for optically-pumped, color-converting devices, not electrically-driven ones), where more harsh environments of considerable heat plus intense photon ux emitting from LED chip are placed, even structurally strengthened QDs are not robust sufficiently, unexceptionally losing their initial uorescent intensity over time of device operation.…”

“…Recently, many researchers turned their attention to the type I-III-VI semiconductor nanocrystals, in particular, CuInS 2 (CIS), which is presently the most attractive and lesser toxic alternative combination [13]. CIS is direct band-gap ternary semiconductor with low toxicity, high optical absorption coefficients (10 5 cm −1 ) [14], and high photochemical stability [15].…”

“…Due to the size effect, the peak wavelengths λp of QDs can be tuned in a certain range. QDs of different systems demonstrate different emission ranges and FWHMs [42][43][44]. Here is this work, ternary II-VI and I-III-VI QDs are used to design the spectra of growing lamps.…”
